The solution set of | x - 1 | ≤ 2 is -1 ≤ x ≤ 3, as required.
A connection between two expressions or values that is not equal to each other is referred to as "inequality" in mathematics. The inequality can be resolved by adding the same amount to each side, subtracting the same amount from each side, multiplying or dividing each side by the same positive integer, and more. If you multiply or divide either side by a negative value, you must flip the inequality sign.
To write the absolute value inequality in the form x−b ≤c or x−b ≥c, we need to identify the midpoint between the lower and upper bounds of the solution set.
The midpoint is (3 - 1)/2 = 1.
Then, we can write the absolute value inequality as:
| x - 1 | ≤ 2
To verify that this inequality has the solution set -1 ≤ x ≤ 3, we can solve it as follows:
If x - 1 ≥ 0, then | x - 1 | = x - 1, and we have:
x - 1 ≤ 2
x ≤ 3
If x - 1 < 0, then | x - 1 | = - (x - 1), and we have:
(x - 1) ≤ 2
x - 1 ≥ -2
x ≥ -1
Therefore, | x - 1 | ≤ 2.

Answer:
x = .
Step-by-step explanation:
Given : 11.42424242 …
To find : Convert it to a rational expression in the form of a over b, where b ≠ 0.
Solution: We have given 11.42424242 …
We can see here two number 42 are repeating.
Let x = 11.42424242 …
On multiplying both sides by 100
100x = 100 * 11.42424242 …
100x = 1142.424242.....
100x = 11.4242.....+1131.00000.....
100x = x + 1131.0000....
On subtracting both sides by x
100x -x = 1131
99x = 1131.
On dividing both side by99.
x = .
Therefore, x = .
The correct answer is:
2.4 million.
Explanation:
To find the rate of change, first we find the amount that the population grew in the time period:
314-302 = 12
Now we calculate the number of years:
2012-2007 = 5
Divide the amount of change by the number of years:
12/5 = 2.4
The population grew by 2.4 million people per year.
